B.6 - Line Judges
(a) When Utilized. Two line judges should be
used for semifinal and final matches, when requested by a player or
team, or when the referee or tournament director so desires. However,
the use of line judges is subject to availability and the discretion of
the tournament director.
(b) Replacing Line Judges. If any player
objects to a person serving as a line judge before the match begins,
all reasonable effort shall be made to find a replacement acceptable to
the officials and players. If a player objects after the match begins,
any replacement shall be at the discretion of the referee and/or
(c) Position of Line Judges. The players
and referee shall designate the court location of the line judges. The
tournament director shall settle any dispute.
(d) Duties and Responsibilities. Line
judges are designated to help decide appeals. In the event of an
appeal, and after a very brief explanation of the appeal by the
referee, the line judges must indicate their opinion of the referee's
(e) Signals. Line judges should extend
their arm and signal as follows: (i) thumb up to show agreement with
the referee's call, (ii) thumb down to show disagreement, and (iii)
hand open with palm facing down to indicate "no opinion" or that the
play in question wasn't seen.
(f) Manner of Response. Line judges should
be careful not to signal until the referee announces the appeal and
asks for a ruling. In responding to the referee's request, line judges
should not look at each other, but indicate their opinions
simultaneously in clear view of the players and referee. If at any time
a line judge is unsure of which call is being appealed or what the
referee's call was, the line judge should ask the referee to repeat the
call and the appeal.
(g) Result of Response. The referee's call
stands if at least one line judge agrees with the referee or if neither
line judge has an opinion. If both line judges disagree with the
referee, the referee must reverse the call. If one line judge disagrees
with the referee and the other signals no opinion, the rally is
replayed. Any replays, with the exception of appeals on the second
serve itself, will result in resumption of play at first serve.
